Impact of the learning curve on outcome after transcatheter mitral valve repair: results from the German Mitral Valve Registry.
Article in Clinical research in cardiology : official journal of the German Cardiac Society, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
aimsThis analysis from the German Mitral Valve Registry investigates the impact of the learning curve with the MitraClip(®) technique on procedural success and complications. METHODS AND
resultsConsecutive patients treated since 2009 in centers that performed more than 50 transcatheter mitral repairs were included. Results of the first half of the patients were compared to those of the second. Altogether 496 patients from 10 centers were included. Patients treated later had less common severe heart failure symptoms (patients with NYHA IV: 22.1 vs. 14.5 %, p < 0.05). The EuroSCORE I (22.0 vs. 23.0 %, p = ns) and Society of Thoracic Surgeons (STS) score (7.5 vs. 9.5 %, p = ns) did not differ between both groups. Procedural success was 95.6 % (238/249) in the first cases and 94.7 % (232/245, p = ns) subsequently. Also procedural time (104.3 vs. 119 min, p = ns) and complications did not decrease over time.
conclusionA learning curve using the MitraClip(®) device does not appear to significantly affect acute MR reduction, hospital and 30-day mortality. Most likely, the proctor system leads to already high initial procedure success and relatively short procedure time.
